IMPROVEMENT IN Hoof-TRI'MMERS.

Specification forming part of Letters Patent No. 150,800, datid May l2, 1874 g application ied September 13, 1873.

To all whom 'it may concern: i

Be it known that we, FREDERICK B. SUT- TON and WILLIAM `O. SUTTON, of Wellington, in the county of- Iroquois and State of Illinois, have invented a new and Improved Horse-Hoof Trimmer, of which the following on which said frame isa cutter fixed in slotsV in the aforesaid side pieces, and provided with a cranked screw for forcing it up to the toe-piece, to shave off the bottom of the hoof. At the toe is a gage, to regulate the amount to' be shaved oii', and on one of the side clamping pieces is a contrivance for quickly releasing the clamping-.frame from the hoof in case the horse becomes restive.

Figure l is a side elevation of our improved hooftrimmer. under side, and Fig. 3 is a section of Fig. 2 in the line fr.

Similar letters of reference indicate corresponding parts.

A and B represent the two clampingpieces. They are pivoted at one end to the strong toc piecevD at C, and at the other end they are connected to the right-and-left-- hand screw E, which is 4swiveled in the nut F, so as to work them toward and from each other, according to the direction in which the screw is turned. Said side pieces are slotted, as at Gr, and a cutting-blade, H, is tted in the slots, to slide toward and from the curved plate I, rising up from the toe-piece D, so as to bear against the toe of the hoof, as indicated in Fig. 3, in' which the dotted lines J indicate the hoof to be trimmed. K is a screw fitted in the toe-piece, the nut M on the blade, and in the nut F, and pro; vided'with a hand-crank, L, for forcing the blade when trimming off the hoof. This screw is, by preference, provided with three Fig. 2 is a plan of the threads for obtaining a quick motion; but itmay have less if it is not important to move it so quick. N is a gage, suspended from the stud Ov of the toe i piece by the screws P Q and the thumb-bit R, so as to project under the toe of the hoof, and be shifted up and down, as shown in Fig. 2, to regulate the projection of the hoof below the blade at the front, and thus regulate the amount cutoff.

The edges of the pieces A B, which clamp against the sides of the hoof, are serrated, to indent the hoof, and prevent slipping oft from it. On the clamping -piece B is a thin plate, S, pivoted at T, and jointed at U with a levenplate, V, which is pivoted to the piece B at W, and at '.L has a curved slot, X, through which the pivot-bolt T passes, so as to alA low the plate to swing on its pivot W, and

lswing the plate S, which has a serratedl edge,

against the hoof or away from it. Said 1everplate has a handle -piece, IY, by which to push it forward and backward, and it is to be held by the screw T with considerable friction, to be kept in any position to which it may be adjusted. This Vplate is pushed inward, as represented in Fig. 2, when the machine is clamped onto a horses foot, so that the plate S bears on the hoof, instead of the piece B, the edge being pushed beyond the said piece B, and it is held by the lever-plate and the screw T, so that the pressure of the screw E does not force it back, but not so strong but the operator can readily pull it back by the leverplate to release the hoof quickly in case the horse becomes un manageable.

We propose to joint the pieces A B to thc toe-pieces D by rule-joints, using shouldered bolts, on which the nuts will screw up tight without pinching the joints together.

Having thus described our invention, we claim as new and desire to secure by Letters Paientl. The combination of the toe-piece D, side pieces A and B, and theV right-andleft adjustingscrew E, substantially as specified.
